Can't connect to some websites

Now that I've gotten my hardware problem out of the way, looks like I have a network problem to deal with. My computer (very specifically, just MY computer) can no connect to certain websites. It's not a lot of them, but it's enough to irritate me. For example, I wanted to try a game called Tera. I downloaded it on Steam and tried to play. Well, not only can I not connect to Tera's website, but I can't connect to their servers either. Anything Tera or enmasse (the company) comes back with a timeout. However, I can access the sites with any other device in my house on the same internet. The program is indeed allowed through the firewall. This is not the only website I have this issue with by the way, it's just the first one that comes to mind. I have no idea what else to check, I'm not good with this sort of thing. Thanks.

Accessing a website is not the same as playing a web game.
If you can download the application, then clearly you have access to the site

Playing games frequently require you to port-forward in your router to your pc's lan address.
The game should tell you which ports are necessary in the Requirements.

Problem is I can neither connect to the games servers nor access their website... I was able to download Tera only through Steam, which is an alternative download method. That's how I know I can't get on that way either.

You replaced the CPU with a lesser one? Did you do a fresh Windows install?

After replacing the CPU? No... Windows automatically recognized it. It is the same type of CPU just a weaker model; from an FX-8350 to an FX-4100. I can't see this having anything to do with my connection issues either...

You might solve this connection problem by installing Windows fresh. As I said in an earlier thread by you, a bad CPU is a rare thing except by poor cooling or handling...

I think it's safe to say it was the CPU at this point, going a good week almost without bluescreens. I just fresh installed windows right before switching the CPU, I would really love to not have to do it again after I finally got some things downloaded. There has to be a more specific solution than the "Idk reinstall Windows I guess" fix-all for software issues. If I have to then so be it, but again, I'd rather wait a little to see if someone has a solution a bit more specific to the problem. As a sidenote, I also can't connect to Twitch.tv.

A CPU is the most important hardware piece of a computer system, just like your brain is to you. If you're willing to live with these "anomalies" so be it...

Excuse me? The only anomalies I'm having are connection-oriented. If you could explain to me how a CPU could cause an issue in which only a select few sites and servers are not able to be connected to I would quite immediately reinstall windows, but as I don't see any logic behind that, I'd rather find the real solution.

I swear it feels like my computer is just taunting me and making fun of me; I fix a problem and another comes. Well thanks for the help across my two threads. Hopefully I won't be posting any issues for a while. Maybe my apparently unusual solutions can help someone else with the same issues.
